Thermal ablation versus surgical resection of small-size colorectal liver metastases (COLLISION): an international, randomised, controlled, phase 3 non-inferiority trial.

Background: For patients with small-size colorectal liver metastases, growing evidence suggests thermal ablation to be associated with fewer adverse events and faster recovery than resection while also challenging resection in terms of local control and overall survival. This study assessed the potential non-inferiority of thermal ablation compared with surgical resection in patients with small-size resectable colorectal liver metastases.

Methods: Adult patients (aged ≥18 years) from 14 centres in the Netherlands, Belgium, and Italy with ten or fewer small-size (≤3 cm) colorectal liver metastases, no extrahepatic metastases, and an Eastern Cooperative Oncology Group performance status of 0-2, were stratified per centre, and according to their disease burden, into low, intermediate, and high disease burden subgroups and randomly assigned 1:1 to receive either thermal ablation (experimental group) or surgical resection (control group) of all target colorectal liver metastases using the web-based module Castor electronic data capture with variable block sizes of 4, 6, and 8.

The Effect of (Chemo)Radiotherapy on Enlarged Lateral Lymph Nodes in Patients With Locally Advanced Rectal Cancer.

Background: Standard of care for most patients with locally advanced rectal cancer in The Netherlands consists of neoadjuvant chemoradiotherapy (nCRT) followed by resection. Enlarged lateral lymph nodes (LLNs), especially in the iliac compartment, appears to be associated with an increased risk of local recurrence. Little is known about the risk of local recurrence after nCRT.

Assessment of Objective and Subjective Cognitive Function in Patients With Treatment-Resistant Depression Undergoing Repeated Ketamine Infusions.

Background: Subanesthetic ketamine infusions can elicit rapid and sustained antidepressant effects, yet the potential cognitive impact of ketamine has not been thoroughly examined. This study measured changes in objective and subjective cognitive function following repeated ketamine treatment.

Methods: Thirty-eight patients with treatment-resistant depression were administered cognitive assessments before and after undergoing 7 i.

Sex differences in developmental patterns of neocortical astroglia: A mouse translatome database.

Astroglial cells are key players in the development and maintenance of neurons and neuronal networks. Astroglia express steroid hormone receptors and show rapid responses to hormonal manipulations. However, despite important sex differences in the cortex and hippocampus, few studies have examined sex differences in astroglial cells in telencephalic development.
